Middle-Range Theory of Occupational Stress in Health Professionals.

Introduction: Occupational stress affects health professionals; however, no literature was found on the middle-range theory for this outcome in health professionals.

Methods: Methodological study for the theoretical validation of a nursing diagnosis using the theoretical framework of Walker and Avant and the Betty Neuman systems models. The research was conducted in five stages: comprehension of the system model; selection and review of studies; development of the conceptual-theoretical-empirical structure; elaboration of a diagram and proposition of a nursing diagnosis; and evaluation of the empirical adequacy of the theory and validity of the system model.

Terminological relationships between nursing diagnoses for children with kidney diseases.

Objective: To identify the relationships between the statements of nursing diagnoses for children with kidney diseases prepared according to the International Classification for Nursing Practice (ICNP®) with the diagnoses of NANDA International (NANDA-I).

Methods: Methodological study operationalized by the steps: 1) Survey of clinical findings through interviews and physical examination with children; 2) Elaboration of nursing diagnoses through Gordon's clinical judgment; 3) Cross-mapping of diagnostic statements between the NANDA-I and ICNP® classification systems; 4) Content validation using the Delphi technique, in two rounds, with specialist nurses.

Results: 90 children participated.

Repercussions of COVID-19 on the daily lives of women living in a rural settlement.

Objective: To understand the repercussions of COVID-19 on women's daily lives in a rural settlement.

Methods: A qualitative study was conducted in a rural settlement of the Landless Workers' Movement (MST) in a municipality in Northeastern Brazil between January and March 2021. Forty-eight women participated through semi-structured interviews.

Terms of specialized nursing language in the care of the newborn with central venous catheter.

Objective: To construct and validate a specialized nursing terminology for the care of newborns with peripherally inserted central venous catheters (PICC), based on the Betty Neuman Systems Model.

Methods: Methodological study, carried out in a public maternity hospital, operationalized by the steps: extraction of terms from medical records of neonates using PICC; normalization; cross-mapping with the 2019/2020 version of ICNP®; organization in the Seven Axes; and content validation with nurses using content validity index and kappa coefficient.

Results: 1,718 terms were extracted, and 372 relevant terms were normalized, with 265 constants and 107 non-constants.

Ineffective health control: concept analysis.

Objectives: to identify and synthesize the concept of Ineffective Health Control.

Methods: Concept Analysis from the perspective of Walker and Avant, operationalized by an integrative review in the databases Scopus, LILACS, PubMed, CINAHL, Web of Science, Science Direct e Cochrane, using the descriptors: Adhesion to Medication; Cooperation and Adherence to Treatment and Acquired Immunodeficiency Syndrome.

Results: five critical attributes were identified for the concept, namely: patient's refusal to follow the therapeutic plan; abandoning treatment and worsening signs and symptoms; difficulty in reaching agreed goals; difficulty following health professionals' guidelines; multifactorial and dynamic process.

Effectiveness of mobile applications in pregnant women's adherence to prenatal consultations: randomized clinical trial.

Objective: to evaluate the effectiveness of a mobile application for cell phones in the adherence of pregnant women to prenatal consultations.

Method: a randomized controlled clinical trial, simple-blind with two parallel groups, conducted from January to December 2018. Data collection was carried out through a structured interview at the end of the third trimester of pregnancy.
